Description

Technical Field

[0001] This utility model relates to the field of tarpaulin processing technology, and in particular to a tarpaulin riveting machine. Background Technology

[0002] In the tarpaulin manufacturing industry, riveting is a crucial process for ensuring the stability of the tarpaulin structure and for splicing or installing accessories. Currently, the tarpaulin riveting machines commonly used in the industry require workers to hold the tarpaulin by hand for positioning, and then complete the riveting operation point by point by moving the tarpaulin.

[0003] This traditional operating method has significant limitations: Firstly, it consumes a large amount of human resources, often requiring at least one worker to hold the tarpaulin and control its movement for the entire process, increasing labor costs and limiting production efficiency, making it difficult to meet the demands of large-scale, batch production. Secondly, during manual handling and movement of the tarpaulin, its positioning accuracy is easily affected by factors such as the worker's experience and physical condition, leading to deviations in the riveting position and consequently affecting the overall quality and lifespan of the tarpaulin. Furthermore, prolonged repetitive handling of heavy tarpaulins increases the worker's workload and poses certain occupational health risks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tarpaulin riveting machine that can reduce manual intervention and achieve automated riveting, thereby solving the technical problem mentioned in the background art that the semi-manual operation mode of existing tarpaulin riveting machines can hardly meet the requirements of modern production for high efficiency, precision, and low labor intensity.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A tarpaulin riveting machine includes a riveting assembly and a mold base, as well as a worktable. Both the riveting assembly and the mold base are mounted on the worktable, with the mold base positioned below the output end of the riveting assembly. The worktable also includes two first clamping assemblies fixed to the worktable and two horizontally movable second clamping assemblies. The two first clamping assemblies are located on either side of the mold base, and the two second clamping assemblies are respectively positioned between the two first clamping assemblies and the mold base. The two first clamping assemblies are used to clamp and fix the tarpaulin, and the two second clamping assemblies are used to clamp and move the tarpaulin. The mold base also includes a vertically movable pressing assembly, which, when the riveting assembly is working, presses down on the tarpaulin to prevent displacement.

[0007] Working principle:

[0008] In use, place the area of ​​the tarpaulin to be riveted on the mold base, and then use two first clamping components to clamp and fix the tarpaulin. Next, use a pressing component to press the tarpaulin down to prevent displacement. Then, the riveting component operates to rivet the tarpaulin. After riveting, use two second clamping components to clamp the tarpaulin, and then release the two first clamping components. Move the two second clamping components to one side to complete the riveting of one point. Then, use the two first clamping components to clamp and fix the tarpaulin, release the two second clamping components to release the clamping, and return the two second clamping components to their original positions to proceed to the next riveting point.

[0009] Beneficial effects:

[0010] 1. The first clamping component can firmly fix the tarpaulin, and the pressing component further presses the tarpaulin to prevent displacement during riveting. The second clamping component can achieve more precise position control when moving the tarpaulin, avoiding the riveting position deviation caused by factors such as operating experience and physical strength when moving manually. This significantly improves the positioning accuracy of riveting, thereby ensuring the overall quality and service life of the tarpaulin.

[0011] 2. By setting up the first clamping component, the second clamping component, and the pressing component in coordination, the tarpaulin is automatically clamped, moved, and positioned during the riveting process. This reduces the tedious steps and waiting time of manual operation, and enables the rapid completion of continuous operations at multiple riveting points. This effectively improves the production efficiency of tarpaulin riveting, better meets the needs of large-scale and batch production, and brings better economic benefits to enterprises.

Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] Example:

[0017] like Figure 1 As shown, a tarpaulin riveting machine includes a riveting assembly 3 and a mold base 2, as well as a worktable 1. Both the riveting assembly 3 and the mold base 2 are mounted on the worktable 1. The worktable 1 has two first clamping assemblies fixed to it and two second clamping assemblies that can move horizontally. The mold base 2 also has a vertically movable pressing assembly. The mold base 2 is located below the output end of the riveting assembly 3, providing a stable base position for the riveting operation. It should be noted that both the riveting assembly 3 and the mold base 2 are existing technologies. The riveting assembly 3 includes a support block 31, a riveting cylinder, and a riveting cutter head. The top of the support block 31 is fixedly connected to the cylinder body of the riveting cylinder, and the piston rod end of the riveting cylinder is fixedly connected to the riveting cutter head. The support block 31 supports the riveting cylinder. The operation of the riveting cylinder drives the riveting cutter head to rise or fall, riveting the tarpaulin on the mold base 2, thereby achieving the purpose of riveting the tarpaulin.

[0018] Two first clamping assemblies are located on both sides of the mold base 2 to clamp and fix the tarpaulin. Specifically, each first clamping assembly includes a first electric telescopic rod 41. The fixed end of the first electric telescopic rod 41 is bolted to the top surface of the workbench 1. The telescopic end of the first electric telescopic rod 41 faces upward and is bolted to a first mounting plate 42. A first motor 43 is bolted to the top surface of the first mounting plate 42. The output end of the first motor 43 faces downward and is connected to a vertical first drive shaft 44 via a coupling. The first drive shaft 44 consists of two threaded rod segments with opposite helical directions. Each of the two threaded rod segments of the first drive shaft 44 is threaded with a first vertical moving block 45. The sidewalls of the two first vertical moving blocks 45 abut against the sidewalls of the first mounting plate 42. This structural design allows the first drive shaft 44 to rotate when the first motor 43 is started, driving the two first vertical moving blocks 45 to move vertically in opposite directions, thereby achieving the clamping and releasing of the tarpaulin.

[0019] Two second clamping assemblies are respectively disposed between the two first clamping assemblies and the mold base 2, and are used to clamp the tarpaulin and drive the tarpaulin to move. Specifically, the second clamping assembly includes a second electric telescopic rod 51. The fixed end of the second electric telescopic rod 51 is connected to the worktable 1. The telescopic end of the second electric telescopic rod 51 faces upward and is fixed to a second mounting plate 52 by bolts. A second motor 53 is fixed to the top surface of the second mounting plate 52 by bolts. The output end of the second motor 53 faces downward and is connected to a vertical second transmission shaft 54 ​​by a coupling. The second transmission shaft 54 ​​is composed of two threaded rod segments with opposite helical directions. The outer periphery of each of the two threaded rod segments of the second transmission shaft 54 ​​is threaded with a second vertical moving block 55. The sidewalls of the two second vertical moving blocks 55 abut against the sidewalls of the second mounting plate 52. In addition, it includes horizontal moving blocks 61. A third motor 62 is installed inside the workbench 1. The output end of the third motor 62 is connected to a horizontal third transmission shaft 63 via a coupling. The third transmission shaft 63 is a threaded rod. The two horizontal moving blocks 61 are threadedly connected to the outer circumference of the third transmission shaft 63. The top surface of the workbench 1 is provided with two sliding grooves 11. The two horizontal moving blocks 61 are located in the two sliding grooves 11, and the side walls of the two horizontal moving blocks 61 abut against the inner walls of the sliding grooves 11. The fixed ends of the two second electric telescopic rods 51 are fixed to the top surfaces of the two horizontal moving blocks 61 by bolts. When the third motor 62 is started, the third transmission shaft 63 rotates, driving the horizontal moving blocks 61 to move horizontally along the sliding grooves 11, thereby realizing the horizontal movement of the second clamping assembly and driving the tarpaulin to move.

[0020] like Figure 1 and Figure 2As shown, when the riveting assembly 3 is working, the two third vertical moving blocks 71 move vertically downward to press down the tarpaulin and prevent it from shifting. Specifically, it includes two vertically movable third vertical moving blocks 71. The support block 31 is fixed to the top surface of the workbench 1 by bolts. The support block 31 is provided with two limiting grooves 311, which extend vertically along the support block 31. A connecting groove 312 connects the two limiting grooves 311. A connecting rod 72 is fixed between the two third vertical moving blocks 71 by bolts. The connecting rod 72 is vertically slidably disposed in the connecting groove 312. A fourth motor 81 is fixed to the side wall of the mold base 2 by bolts. The output end of the fourth motor 81 is connected to a horizontal fourth transmission shaft 82. An operating groove 21 is provided on the side of the mold base 2. The fourth transmission shaft 82 is rotatably disposed in the operating groove 21. A first bevel gear 84 is fixed to the outer periphery of the rod segment of the fourth transmission shaft 82 disposed in the operating groove 21. The bottom of one of the limiting grooves 311 is connected to the top of the operating groove 21. A vertical shaft 83 is rotatably mounted in the groove 311. The bottom end of the shaft 83 extends rotatably into the operating groove 21, and the bottom end of the shaft 83 is rotatably connected to the inner wall of the operating groove 21 via a bearing (it should be noted that the bearing rotatable connection is prior art, and its structure and principle are well known to those skilled in the art, and will not be described in detail here). A second bevel gear 85 is fixedly mounted on the outer periphery of the rod segment of the shaft 83 located in the operating groove 21. The first bevel gear 84 meshes with the second bevel gear 85. The shaft 83 is a threaded rod. One third vertical moving block 71 is threadedly connected to the outer periphery of the rod segment of the shaft 83 located in the limiting groove 311, and the side wall of the third vertical moving block 71 abuts against the inner wall of the limiting groove 311. A limiting rod 86 parallel to the shaft 83 is fixedly mounted in another limiting groove 311. The limiting rod 86 is a smooth round rod, and the other third vertical moving block 71 is slidably connected to the outer periphery of the limiting rod 86. When the fourth motor 81 starts, it drives the rotating shaft 83 to rotate through the transmission of the fourth transmission shaft 82, the first bevel gear 84, and the second bevel gear 85. This drives the third vertical moving block 71 connected to the rotating shaft 83 to move vertically. Under the action of the connecting rod 72, another third vertical moving block 71 moves vertically along the limiting rod 86, thereby pressing and releasing the tarpaulin.

[0021] Working principle:

[0022] In use, the area of ​​the tarpaulin to be riveted is placed on the mold base 2. The first motor 43 is started, causing the first drive shaft 44 to rotate, which drives the two first vertical moving blocks 45 to move relative to each other, clamping and fixing the two ends of the tarpaulin. Then, the fourth motor 81 is started, which drives the third vertical moving block 71 to move vertically downward through a series of transmissions, pressing the tarpaulin to prevent it from shifting. Subsequently, the riveting assembly 3 works to rivet the tarpaulin. After riveting is completed, the second motor 53 is started, causing the second drive shaft 54 ​​to rotate, which drives the two second vertical moving blocks 55 to move relative to each other, clamping the tarpaulin. At the same time, the first clamping assembly releases its grip on the tarpaulin. The third motor 62 is started, causing the horizontal moving block 61 to move the second clamping assembly, thereby moving the tarpaulin to one side, completing the riveting operation for one point. Afterward, the first clamping assembly clamps and fixes the tarpaulin again, and the second clamping assembly releases and returns to its position to perform the riveting operation for the next point, and so on.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
